Definitions

  • This invention relates to a cap for writing instruments such as a mechanical pencil, a ball-point pen, and the like, and particularly to a cap for writing instruments to which a safety measure is applied so that even if a curious infant should erroneously swallow a cap, which as a result is stopped up at his (or her) throat, ventilation of air is secured.
